PM Update: Brief respite in stormy period
Another heavy rain risk around the corner

Since a cold front went through this morning, dew points have been steadily falling and the very muggy air mass of yesterday is gone for now. Under partly-to-mostly cloudy skies this afternoon, temperatures are rising to highs near 80 and into the lower 80s across the area. Our break, and more pleasant conditions contained within it, won't last too long.
Through Tonight: This is looking like a pretty decent evening to be outdoors as temperatures fall to the low-and-mid 70s around sunset. It's partly cloudy with lows falling into the mid-50s for the cooler suburbs to nearer 60 downtown. Winds die down from today but probably stay up enough to keep fog from forming where it rained a lot yesterday.
Tomorrow (Wednesday): We could start off briefly with some nice sunshine before clouds increase, probably putting us at mostly cloudy by mid-day or early afternoon. Then there's the question of when rain arrives. Right now, best guess is late-afternoon or evening, but it could honestly be knocking on the door by late morning or mid-day, though the heaviest should hold off till nighttime. Highs should range from near 70 into perhaps the mid-70s.

L.A. heat: The major low pressure system parked over the East recently has brought in cooler weather than we've seen much of the warm season. Not so out west. After a cool summer in places like Los Angeles, southern California was roasting the last few days, including some incredible all-time record heat in L.A. yesterday where the thermometer hit 113 degrees. See more on other local heat records.

I thought the same Jerry, but local obs don't necessarily show much easterly wind, and temps peaked really early in the day (by noon most places).. The hottest temps were definitely west of the coastal mountain ranges though. The previous all time at Long Beach was in mid-Oct, which must have been during a Santa Ana wind episode.

Very strange and unusual, Ian, for temps to get that high w/out a Santa Ana. Actually good that east winds weren't that strong because fire danger would have been even greater.

As a native Angeleno currently in DC, I'm worried that LA's crazy heat spell will also mean a decent-sized quake. For at least a decade until I left a few years ago, I observed that every time there was a big out-of-synch period of high temp, there was a quake soon after magnitude 4 or higher. These pops were heat spells unrelated to Santa Anas, lasted more than 1-2 days and usually occurred in early fall or Jan-Feb.

After reading the forecast above, its begining to sound like I picked the wrong night (tommorrow night) to go to a Nats game....are we looking at a washout here for the home closer?

I'm still taking this big rain event with a grain of salt, wouldn't surpised if it plays out like yesterday. Looking at radar over the last several hrs, the prec. again appears 2 b moving on an ENE track. I really hope I'm wrong, because we really need the rain.

Wilmington, NC had more than 10" of rain from yesterday's storm and the next one could make landfall near Wilmington. Since I'll be in NYC Wed p.m.-Fri a.m., I'm hoping the next storm either tracks well west, or scoots way out to sea.

ftwash - I think tomorrow night might require some rain gear, yes :-/

I think it's a sure bet that yesterday's headline, "The rain that wasn't" will transition by Friday to one reading "The rain that was".

Let's hope the 18z NAM was just a hiccup and we don't see 7+ inches of rain in what may be a 12 to 18 hour window. That would not be good at all. Sump pumps on stand by...

Sounds like some serious downslope warming yesterday in southern Calif. 111 at Long Beach Airport but "only" 103 at Lancaster, north of the mountains.
